Highly functional manufacture complications are an integral part of Montblanc’s horological offering, as the new Montblanc 4810 TwinFly Chronograph Transatlantic Limited Edition illustrates so well.
This flyback chronograph allows the wearer to time one event, and then stop, reset and restart the chronograph with just one press on the pusher at 4 o’clock. This TwinFly function not only restarts the central chronograph seconds hand (in blue), but also the central minutes chronograph hand (in red gold), sending both hands back to zero and instantly restarting them for a new time measurement.
Another pusher at 2 o’clock starts and stops the chronograph, while the pusher at 4 o’clock also returns the chronograph to 0 when it has previously been stopped.
Driving the functions of the Montblanc 4810 TwinFly Chronograph Transatlantic Limited Edition is the Maison’s self-winding Calibre MB LL100.1 that has been developed and assembled entirely in-house and features both a chronograph and a dual time indication via an additional central hand (the dual time function on the MB LL100.1 has the same functionality as the one on the Heritage Chronometrie Dual Time).
The chronograph mechanism uses a traditional column wheel and a vertical clutch system to start and stop the chronograph with perfect precision. Two barrels ensure a 72-hour power reserve so that the wearer can comfortably leave the watch over the weekend and then strap it right back on the wrist on Monday morning without missing a beat.
On the aesthetic side, all the familiar Montblanc design codes can be found in the Montblanc 4810 TwinFly Transatlantic Limited Edition, starting with a 43 mm steel case and a large opening for the silvery-white guilloché dial, whose pattern depicts an exploded view of the iconic Montblanc Star.
The hours are marked by alternating red gold-plated Roman numerals and baton indexes, while the hands are a mix of baton and skeleton designs and point to scales that run around the dial, indicating the seconds and the minutes with utmost precision. Each hour is also accentuated by the addition of a SuperLumiNova®* dot for improved visibility at night, and the minute scale includes red numbers at each 10-minute mark for greater legibility during the day.
For the functions, the hour and minute hands are indicated with red gold-plated, sword-shaped hands, while the second time zone is shown via a highly readable skeletonized blue sword-shaped hand (for home time when travelling). Setting the local time is an extremely fast and precise affair, as the seconds don’t stop when the crown is pulled out.
Moving onto the subdials, small seconds are displayed by a red gold-plated hand with a red tip in the subdial at 6 o’clock. This subdial also doubles as a date indicator with a large red arrow pointing to the date.
At 12 o’clock, the subdial illustrates a map of the world that reveals whether it is day or night in the home time when travelling and links back to the pioneering spirit of transatlantic travel.
Limited to 1,110 pieces, the Montblanc 4810 TwinFly Chronograph Transatlantic Limited Edition comes fitted with an elegant black alligator strap.
